对于线性系统，输入输出在某频率点为正弦，利用本程序可以得到改频率点的幅值比和相位差。data文件为两组数据，通过matlab读取xls文件，可以用来验证本程序。(For linear systems, input and output sine wave at a frequency point, the use of this program can change the frequency by the amplitude ratio and phase difference. data files for the two sets of data, read by matlab xls files, can be used to test the program.)

用简单易行的风格，一开始介绍了MATLAB 基础，你将学习到如何绘制图象，求解代数方程及计算积分，也将学习到如何求解微分方程，求ODE 的数值解，使用特殊函数工作。 本书含有几百个例子及其详细解说过程，章末带有习题，书末还带最终测试题目，一句话，本书给予你的是MATLAB 精华.(Simple style , a start MATLAB basis , You will learn how to draw images, solving algebraic equations and calculate the integral , but also to learn Learning how to solve differential equations , and the ODE numerical solution to the use of special functions . The book contains hundreds of examples and a detailed explanation of the process , the end of the chapter with exercises, the end of the book With the final test subject , in a word , this book give you the MATLAB Digest )

同时采用身高和体重数据作为特征，用Fisher线性判别方法求分类器，将该分类器应用到训练和测试样本，考察训练和测试错误情况。将训练样本和求得的决策边界画到图上，同时把以往用Bayes方法求得的分类器也画到图上，比较结果的异同。(At the same time the height and weight data as features, Fisher with linear identifying method for classifier, will this classifier applied to training and test sample, to investigate the training and test error conditions. Will the training sample and values of the decision on the graph shows the boundary, and at the same time before the Bayes method with optimal classifier also paint chart, the similarities and differences of the comparison results. )

一个BP练习程序，通过修改输入输出的参数，可以观察这些变动对预测效果的影响。(a Backprogation code,can be used to practise the parameters divergence and the fortelling effect.)
